Figure 5
The spatial arrangement of the metal atoms of the title compound, viewed along c*, with the unit cell outlined. The upper half covers the range 0.24 < z < 0.76, with [Fe3O(SO4)6(H2O)3]5− units represented by their Fe triangles (filled for z ≃ , open for z ≃ ). The Na3 positions (0.089 occupancy) have been omitted. Note the three almost coinciding atoms Cs2, Cs1 and Cs2(−x + 1, y, −z + 1). The lower half shows the range −0.01 < z < 0.01. |
